Bullion Bars Grab the Gold lacks an aesthetically pleasing design, just like any other vintage slot machine. The game appears a little dated and basic. It's not a bad thing, either, because there's nothing to be upset about for individuals who enjoy the classics. Nevertheless, the colour combination is visually pleasing, and the simple design still has some charm. Rich in gold, the 3x3 reel set with nine ways to play is locked away in a dark vault, and you're ready to use the bonus game to open the gold safe.
When three matching symbols line up on one payline, you have a winning combination. Five Lucky 7s are present in the slot machine: red (375x), blue (250x), and yellow (125x). Additionally, there are single BARs of 25x and double BARs of up to 62.5x. You will get 37.5x for a combination of three different Lucky 7s, but only 12.5x for a combination of double and single BARs.
The Bullion Ladder, which has nine gold bars displayed, is located to the right of the reels in the base game. With every spin, the ladder descends one position, removing the bottom bar and adding a new one to the top. Each bar has a random multiplier value ranging from 5x to 999x bet per line. The Grab the Gold bonus game is triggered by landing three Bonus Symbols on a single payline on any base game spin. You then advance to the feature using the current values displayed on the Bullion Ladder.
The Super Bar Trail, which shows your progress in the bonus game, is located above. An arrow will be lit on the trail upon completion of the picking round, and the Super Bar will be released once the safe has unlocked after ten rounds. Super Bar value, which is different from conventional gold bars in that it can range from 1,000x to 9,999x the line bet, will be added on top of the Bullion Ladder. The player will have a 1:3 chance of selecting the Super Bar if they advance to the final round.
